WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 484,559, dated October18, 1892.

Application filed October 15, 1891. Serial N0- 408,792- (No model.)

To all whom, it may concern.-

Be it known that I, ARTHUR J. NILES, a citizen of the United States,residing at Lancaster, in the county of Coos and State of New Hampshire,have invented certain new and useful Improvements in ater-Closets; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to that class of commodes in which the bowlistilted to expel the contents; and my object is to provide a moreperfectly-working and desirable article than those heretofore conceived.

With this purpose in view my invention consists in the peculiar featuresand combination of parts more fully described hereinafter, and pointedout in the claims.

In the accompanying drawings, Figure 1 represents a vertical section ofmy complete device; Fig. 2, a similar view showing the parts in action.

The exterior casing of my device is cylindrical in form and consists ofa top section a and base-section b,connected tightly by aneatfittinglap-joint c. A partition 61 is placed across the top part of the baseand forms the Waste-receiving compartment 6, which is thus shut 01f fromthe chamber above. A circular receiving-openingfis made in the partitiond and is kept normally closed by an upward-seating valve g, havingbeveled edges to make a tight fit. This valve is fixed on the end of alever 72, the opposite arm of which is provided with a counter-weightz'to hold it normally closed. A semicircular door j is also located inthe partition to permit the contents of the waste-compartment to beemptied. A water-tank k is located in the upper part of the compartmentand is'formed by an inner cylinder Z, through which droppings fall tothe bowl m below, fixed on a rock-bar 17,, operating in bearings 0,attached to the inner walls of the upper section a. The top of thewater-tank is closed by the seat 19. A lower water-tank 7c is locatedbelow the main tank It and is provided with an air-vent r. The bowl misflushed through outlet 8 in the bottom of lower tank lo, which holds apredetermined amount of water. The outlet is commanded by adouble-acting verticallymovable valve t, the stem of which passesthrough the lower tank and alternately seats against its top and bottomwalls a u. The bowl is tilted by means of a vertical liftingrod 1;,provided With a hand-pull e at the top and connected to the bowl by achain or other suitable connection '20. The end of the bowl is providedwith a projection 10', which comes in contact with the bottom of thevalve and lifts it to permit the water to flow from the tank It to thelower tank An arm or lug a: extends downward from the rear of the bowland comes in sliding contact with the sloping surface of a cam 00',fixed on top of valve g. The inner side of the seat 19 is provided witha downwardly-projecting flange p, which fits snugly within the top ofthe upper section a, and a recess 19" in the flange comes opposite theupper end of the vent to permit the escape of air through the latter. Inthe rear of the bowl there is a transverse opening m' and back of it anupward projecting guide-lip m". This opening registers with thereceiving-opening f of the waste-compartment below.

Although a rigid seat is shown and described, yet it is evident that itcould be otherwise constructed to co-operate with the mechanism belowwithout departing from the spirit and scope of the invention, and thecylindrical form of the closet is simply a preferred one, as it could bemade to operate with success in other shapes.

In using the foregoing mechanism the operator pulls on the rod 1),thereby drawing the front end of the bowl up against the lower end ofvalve t, which causes the valve to close the opening in the bottom ofthe lower tank and open the passage from the upper tank into the lowertank, thereby allowing the latter to fill. The bowl is then allowed todescend to a horizontal position, as shown in Fig. 1, and in so doingthe valvet closes the upper passage and opens the lower one, whichallows water to How into the bowl, and when in this position the bowl isready for use. The rod 1) now being pulled up, tilts the bowl andempties its contents out through the oblong transverse opening in therear of the bowl. In this action the valve toperates as before, thelower tank being again tilled while the bowl is raised and the bowlbeing flushed on releas ing the hand-pull and in resuming its hori- Iclaim as new, and desire to secure by Letters Patent, is

l. The combination, in a commode, of a valved reservoir placed below theseat, a valved waste-chamber in the bottom of said commode, and atiltable bowl between the reservoir and waste-chamber, the oppositesides of said bowl actuating the valves, substantially as set forth.

2. The combination, in acommode provided with three compartments, theupper one containing a reservoir and measuring-chamber situated underthe seat, a tiltable bowl placed in the middle compartment, and awastechamber in the lower compartment, the upper and lower compartmentsbeing provided with valves which are actuated by the bowl when it isflushed, all arranged and adapted to operate in the manner and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ARTHUR J. NILES.
